After graduation, Li Dazhi, together with the heroine Ye Kexin, his childhood friend Zhao Dongming, and his best friend Sun Yan, started a life of working workers in a first-tier city with a mixture of bitterness and joy. From sharing an old community to resigning and starting a business, from infighting in the workplace to emotional ups and downs, everyone is constantly encountering 'urban monsters' (mortgage, layoffs, anxiety, order, shattered dreams, etc.). After a particularly large project failed, the four were forced to embark on an adventurous counterattack. In the end, they each gained growth and happiness, and redefined the meaning of life. There are many twists and turns in the middle that are both hilarious, and the evolution of friendship and love is delicately described, ultimately returning to the attitude of life of "fighting monsters and upgrading".
